[1]在最近发现的深月震巢中，寻找远端深月震的努力已经确定了大约30个可能位于远端的月震巢。尽管其中只有几个可以用目前可用的数据定位，而且这几个巢提供的关于月球深处的新信息很少，但其余这些巢的推断分布表明，要么是距离月球对极40度以内的月球深部区域几乎是无地震的，要么是月球非常深的内部严重衰减或偏转地震波。由于这对月球的起源和演化有重要影响，未来的月球任务需要着眼于解决这种不确定性。一些有限的数据支持衰减/偏转假设。
[ 1] An effort to find farside deep moonquakes among the recently discovered nests of deep moonquakes has identified about 30 nests that are likely to be on the farside. Although only a few of them are locatable with currently available data and those few provide little new information about the deep interior of the Moon, the inferred distribution of the rest of these nests indicates that either the region of the Moon's deep interior within about 40 degrees from the antipode of the Moon is nearly aseismic or, alternatively, the very deep interior of the Moon severely attenuates or deflects seismic waves. Since this has important bearing on the origin and evolution of the Moon, future missions to the Moon need to be oriented toward resolving this uncertainty. Some limited data favor the attenuation/ deflection hypotheses.
